TMI POST Blood after squirting/ fingering

Okay, ladies! I have a question: is some bleeding after squirting/ fingering normal? I have a IUD in and the last two times, 4 days apart, when my SO has done his magic touch, almost immediately I’m bleeding.

And I’m not talking spotting, I’m talking almost period flow with slight cramps and then it stops after an hour or two.

I’m nowhere near due for my menstrual cycle yet so I’m just wondering if any others have experienced this?

I have an appointment with my OB already but it’s just my curiosity. THANK YOU💗💙
